Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Sometimes you need a simple server which listens on a port and prints out received data.

Example: Consider you want to know, which data is posted by a homepage to a remote script without analysing the html code! A simple way to do this is to save the page to your computer, substitude all action="address" with action="localhost:portnumber", run 'ncat -l portnumber' and open the edited page with your browser. If you then submit the form, ncat will print out the http-protocol with all the posted data.
